Description of problem:

If an SSH secret that is attached to an existing VM is added to a new VM created using the catalog or InstanceType flows as an existing secret and the VM to which that secret was originally attached is deleted, the secret will be deleted and removed from the newly created VM.

How reproducible: 100%


Steps to Reproduce:
1. Create a VM via the catalog or InstanceTypes flows. Customize the VM in the process and add a new SSH secret
2. Create another VM via the catalog or InstanceTypes flow. Customize the VM in the process and add the secret from step 1 as an existing secret.
3. Delete the original VM.
4. Check the SSH secret on the VM created in step 2.

Actual results: 
There is no secret.


Expected results:
The secret still exists and is still attached to the VM.
